Keeping Your Underwater Mission Safe.

Our team of experienced engineers is dedicated to the mission of serving the underwater diver and the subsea operator to provide reliable, accurate, mission critical subsea navigation equipment.

Kenautics underwater products are focused on achieving accuracy in waypoint navigation.

Read All About Our Amazing Products.

Kalman Filter-Based Navigation Engine (K-NAV)

K-NAV is the core processor and software suite at the heart of Kenautics products. K-NAV provides for input of numerous navigation and subsea sensors including:

  • Doppler Velocity Log (DVL)
  • Inertial Motion Unit and Attitude, Heading, and Roll Sensor (IMU/AHRS)
  • Pressure Sensor
  • Global Positioning System (GPS) Receiver (Commercial GPS, with options for SAASM GPS)

K-NAV's proprietary navigation algorithms provide highly accurate velocity and position information to provide complete geo-referenced location awareness for both divers and subsea vehicle operators.

Diver Navigation and Imaging System (DiNIS)

DiNIS is one of the world's most capable, integrated, underwater hand-held diver navigation systems ever designed. Designed primarily for the demanding needs of the world's military Special Forces, as well as for law enforcement, search and rescue, salvage, and academic research, DiNIS provides a complete suite of commercial underwater navigation sensors for the purpose of waypoint navigation, Intelligence, Surveillance, and Reconnaissance (ISR), bathymetry, and underwater imagery in the form of both sonar and video. DiNIS is designed to achieve STANAG 2897 Class B Compliance.

DiNIS Functionality

  • Waypoint Navigation
  • Sonar Imagery
  • Video Imagery
  • Marking of Targets of Interest
  • Mission Analysis, Data is available through an open source/open architecture format and can be made COIN (Common Operator Interface, Navy) compatible.

With advanced Kalman filtering capabilities, Kenautics promises to deliver accuracy in underwater navigation and diver location and positioning.

DiNIS derives from generations of experience in diver navigation systems. It is differentiated from other systems by its unique and tight integration of all sensors and data that provides simultaneous interoperability across all active sensors, with minimal interference, and with all data geo-referenced and sharing a common time stamp. This assures complete and rapid situational awareness both to the diver and to the mission planner.

Interaction with our top-side mission planning and post-processing software suite adds enhanced value to the military end user. With the capability of processing many missions simultaneously, situational awareness can be gained rapidly and with precision. Reconnaissance of underwater targets can be marked on the spot by the diver and tagged with relevant details to gain greater environment and domain awareness.
